WordPress.com and WordPress.org are two ways of hosting a WordPress site.
The thing that varies with these two methods is the actual host. By using WordPress.org, you may download the script free of charge and host it yourself on a local machine or with a hosting provider.
On the other hand, WordPress.com takes care of all that by hosting the site for you. You don’t have to manage a web server, pay for hosting or download software, however, ads are shown on your site.
Both WordPress.org and WordPress.com have certain pros and cons.
If you are not interested in having your own hosting or managing a web server, then WordPress.com may be the way to go.
It is free and can be quickly set up. You will also have various features and options for your site’s customization.
However, it comes with downsides. Your website will include WordPress.com in the URL and you will not be able to upload custom themes or plugins.
The ability to edit or modify PHP code behind your site will also not be possible.
Using a self-hosted version from WordPress.org provides more flexibility and control over your site. You will be able to use your own domain name, upload themes, plugins and install them.
You will also have access to your WordPress files, database, and code, meaning that you will be able to modify it according to your liking. The most popular and powerful WordPress sites are self-hosted, as it provides greater flexibility and the ability to implement custom functionality, code, and designs.
Last but not least, in case WordPress is not the CMS for you, having your own hosting account will allow you to test other content management systems such as Drupal or Joomla.
